PIN BOARD Application filed May 20,

This invention relates topin boards and it is more especially an improvement upon the structure disclosed in Patent 1,7 94,7 7 5, issued to me on March 3, 1931.

It is the practice, when handling pin boards, to place them on the top boards of spinners and doublers, where they remain while being filled with bobbins. It has been a difficult matter to prevent the pin boards 0 from becoming displaced laterally on these top boards because of the vibration of the machines and accidental thrusts by the operators. Consequently various undesirable N expedients have been resorted to. For example where a metal pin board is used, the

operators have frequently bent them transversely so as to cause them to straddle the top board. This has subsequently interfered with proper stacking of the pin boards and has soon rendered them unfit for use.

It is an object of the present invention to provide a pin board which will be properly held to a top board without distortion and without requiring any change in structure which would interfere with stacking.

Because of its lightness and cheapness the open-frame type of pin board is more desirable than a pin board which has a solid base. These have been objectionable however, because they have not been made with smooth bottoms. with a marginal frame projecting downwardly from the remaining portions of the pin board. These have been objectionable because when the filled pin boards are stacked one upon the other the load is applied to the rim portions of a few bobbin heads which frequently break off under the excessive strain. They have also interfered with the sliding is of a filled pin board over the tops of the bobbins on another board thereunder. Instead each pin board must be lowered bodily onto the bobbins thereunder and as this is done sometimes with considerable force and carelessness, it frequently causes breakage of those bobbins which receive the impact and weight of the pin board thereabove.

Other pin boards have pins riveted thereto, leaving heads projecting downwardly from the pin board. These are objectionable Some of them have been formed 1932. Serial, No. 612,586.

for the same reasons as the downwardly projecting frame heretofore mentioned and because of the further fact that they tend to soar and gouge table tops and like on which they are placed and slid during handling. Another object of the present invention is to provide a pin board which is free from projecting portions of all kinds on the bot tom thereof so that the objections pointed out will be avoided. 7 It is a further object to provide a pin board with spaced runners for holding the pin board against lateral displacement when seated on the top board of a machine, these runners also being smooth on their bottoms so as to slide freely over a flat surface or over the bobbins on a filled pin board, and to distribute the load evenly over the upper ends or heads of all bobbins positioned under the runners. With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention. 30

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing: Figure 1 is a plan view of one form of pin board containing the present improvements. Figure 2 is a section on line 2,2, Figure 1. Figure 3 is a section on line 3-3, Figure 1. Figure 4 is an end elevation of a pin board seated on the top board of a spinner or doubler, said board being in section. Figure 5 is an end view of portions of two pin boards in partly stacked relatiomthe bobbins thereon being indicated by broken lines. Referring to the figures by characters of reference, 1 designates a frame which can be made of stiff wire or like material bent to any shape desired. Transverse flat strips of metal 2 are fastened at their ends to the frame and arranged'under all of them are flat runners 3 consisting of metal strips straight from end to end and having their terminals extended under the ends of the frame. These strips can all be attached to the frame by bending their ends upwardly and inwardly over the engaged portions of the frame, thereby forming eyes 4. They can also be joined at their points of intersection as shown, for example, in my patent referred to herein.

Pins having base enlargements 6 are fastened to the runners 3 at any places deslred and can be secured by welding, upsetting, or any other suitable means. It is essential, however, that no protuberances be formed on the bottom surfaces of the runners as otherwise the pin board would not possess the advantages desired.

In using the pin board it is placed on the top board B of a spinner or doubler. This board is provided with the usual ribs R at e the edges thereof. The pin board will rest on these ribs in the usual manner, as shown in Figure 4;, but the ribs will p1'o]ec.t be- 'it becomes necessary merely to rest the runners of one pinboard on the upper ends of the bobbins thereunder and then to slide the pin board to position. This sliding action will not be interfered with by any protuberances or other projecting portions and the weight of the pin board will be distributed over the ends of all bobbins beneath its runners. Thus a number'of pin boards can be stacked and there will be no damage due to overweight. It will be noted that the frame 1 extends above those portions of the pins which engage the strips 2 and 3. Thus protection is provided for the lower flanges of the bobbins on the pins.

It is to be understood that the number of runners 3 and the number of cross strips 2 used in any pin board will depend upon the wishes of the maker and while pins 5 have been shown only at the intersections, of the strips 2 and 3, they can be located at other points on the structure.

hat is claimed is:

1. A pin board including a frame, cross strips carried thereby, spaced longitudinal runners secured at their ends to the frame and extending under the cross strips, and pins secured to the strips and runners, all portions of the frame and pins being above the level of the bottom faces of the runners.

2. A pin board including a frame, spaced runners secured to theframe, and pins extending upwardly from the runners, all portions of the frame and pins being above the level of the bottom faces of the runners.

. 3. A pin board including crossed upper and lower strips, means for connecting the strips, and upwardly extending pins carried by the strips, the lower strips being straight to constitute runners, all portions of the pins and the connecting means being above the level of the straight bottom faces of the lower strips.

4. A pin board including crossed upper and lower strips, means for connecting the strips, and upwardly extending pins carried by the strips, the lower faces of the strips being below the level of the connecting means to constitute runners for sliding onto a support.

5. A pin board including crossed connected strips, a frame connecting the strips and extending above the upper and lower surfaces of the crossed portions thereof, and pins extending upwardly from the strips, said frame also extending above those portions of the pins engaging the strips, thereby to provide a protection for the lower flanges of the bobbins on the pins.

In testimony that I claim theforegoing as my own, I have hereto afiixed my signature.

JOHN ELWIN. JOHNSON.
